HealthTap is a good example of what is coming

HealthTap for the iPhone and iPad provide a good glimpse of why bandwidth is important and how healthcare is going to be changed by the Internet. The service provides access to tens of thousands of doctors and health care specialists, both on a pay as you go basis and a "concierge" subscription service. For $99/month you may be able to get HealthTap access to your own doctor, as well as other specialists.

It remains to be seen how successful HealthTap is in recruiting doctors, as the scheduling could be complex. But one way of looking at HealthTap and other software like it is to see it as the healthcare equivalent of Uber and Lyft, which have completely disrupted the taxi and limo business, to the dismay of the taxi/politician cartel, who like limited access, high licenses fees, and the revolving door of campaign contributions that keep competitors like Uber and Lyft out of major metro cities.
